/** Define whether a pre-gap shall be written before the track and how many
sectors this pregap shall have. A pre-gap is written in the range of track
sectors this pre-gap shall have. A pre-gap is written in the range of track
index 0 and contains zeros resp. silence. No bytes from the track source
will be read for writing the pre-gap.
This setting affects only CD SAO write runs.
Track 1 always has a pre-gap of at least 150 sectors. Further pre-gaps
are not mandatory for MMC compliance as long as track modes are not mixed.
Mode mixing is currently not supported by libburn.
The first track automatically gets a pre-gap of at least 150 sectors. Its
size may be enlarged by this call. Further pre-gaps are demanded by MMC
for tracks which follow tracks of a different mode. (But Mode mixing in
CD SAO sessions is currently not supported by libburn.)
@param t The track to change
@param size Number of sectors in the pre-gap.
0 disables pre-gap, except for the first track.
-1 disables pre-gap, except for the first track.
libburn allows 0, but MMC does not propose this.
@param flag Bitfield for control purposes. Unused yet. Submit 0.

This setting affects only CD SAO write runs.
MMC prescribes to add a post-gap to a data track which is followed by
a non-data track. (But libburn does not yet support mixed mode CD SAO
sessions.)
@param t The track to change
@param size Number of sectors in the post-gap.

show any although 6.33.3.19 would prescribe some.
ts B20111: Table 1 of MMC-1 shows two post-gaps. The first matches the
precriptions with SEND CUE SHEET. The second one is riddling.
Both are part of a track and occupy the range of the last index
of the track. Length is 2 seconds for each.
Nobody seems to have ever tested this situation, up to now.
